The figures shown indicate the preset ventilation levels ("factory settings").

1 = 120 m³/h, reduced ventilation (RV)

2 = 180 m³/h, nominal ventilation (NV)

3 = 240 m³/h, intensive ventilation (IV)

I = Interval or "humidity protection operation" depending on RV

Individual settings available:

RV = 80 m³/h - 320 m³/h

NV = 80 m³/h - 320 m³/h

IV = 80 m³/h - 320 m³/h

Essential condition: RV < NV < IV !

WR 310

short description

Centralised, highly-efficient ventilation units with EC fans and constant volumetric flow regulation, including cross-counterflow exchanger, supply and exhaust air on left, air volume 80 - 320 m³/h, connection diameter 4 x DN 160, 4 SVR 160 plug connectors or 90° B90-160 elbow needed to connect folded spiral-seams ducts (order as accessories), including RLS 1 WR control unit, including integrated web server and MAICO app (air@home) for mobile unit control, live reports via web tool, DIBT approval and passive house certificate, KNX and EnOcean connection possible

Product description

Standard model

  • With cross-counterflow heat exchanger
  • Unit in left-hand version

Features

  • Highly efficient, intelligent, centralised ventilation unit with heat recovery for comfort ventilation.
  • Compact and very quiet unit for wall / standalone mounting (optional).
  • An easily accessible USB port for service/start-up characterises all unit variants.
  • DC motors with integrated, automatic volumetric flow regulation for constant air volume ("volumetric flow consistency").
  • The DC motors can be operated via the optional additional "pressure constant" PCB ZP 2.
  • Good customer service/ease of use thanks to modern unit module technology.
  • Good flexibility thanks to various equipment and connection options.
  • Housing: Sheet steel, powder coated.
  • Colour: white aluminium.
  • Inner cladding made from temperature-resistant and extremely noise- and heat-insulating plastic (EPP). The material is also characterised by its hygienic and non-hygroscopic properties. Tested by the Institut für Lufthygiene Berlin [Berlin Institute for Air Hygiene] according to VDI 6022 Part 1.
  • Additional noise-insulating cladding in the supply air guide.
  • Maximum air tightness.
  • Simple filter change is possible without tools.
  • 4 DN 160 duct connections.
  • Can be equipped with plug-in connectors or duct bend (accessories).
  • The WR 310 and WR 410 unit variants can be upgraded later on (e.g. electr. PTC preheating register (optional) or bypass (optional) or enthalpy heat exchanger (optional).
  • DIBT approval.
  • PH certification.

RLS 1 WR control unit

  • Included in the scope of delivery.
  • Switching the 4 ventilation levels, maintenance display, fault messages.
  • Other control units can be connected in parallel.

Touch screen control unit RLS T1 WS

  • Optional.
  • Up to 6 operating modes possible.
  • 2 automatic operating modes (Auto Sensor / Auto Time).
  • 4 manual operating modes (ECO exhaust air / ECO supply air / MANUAL / OFF).

air@home

  • The units have an integrated web server and can be controlled with an app when at home or out and about, e.g. using a smartphone.
  • Live reports, user administration, control and setting using web tool, via tablet, laptop and PC.
  • Settings:
    • Needs-based automatic mode / Time-controlled automatic mode.
    • Manual operation / OFF.
    • ECO mode supply air or ECO mode exhaust air.
    • Filter queries, error messages.
  • Registration needed. For more info, see "www.air-home.de"

Controller

  • 3 temperature sensors in outside -, outgoing and supply air connections.
  • 1 combination sensor (temperature and humidity) in exhaust air connection.
  • Integrated excess humidity avoidance function.
  • Continuously variable needs-based adaptation of air volumes.
  • Multi-function contact for controlling EW brine earth heat exchanger (uncontrolled pump), operating and fault display, preheating and postheating register, shutters.
  • Can be extended with other PCBs (z.B. ZP 1, ZP 2).

ModBus

  • Integrated MODBUS interface enables integration in the building control technology.

EnOcean

  • Optional EnOcean plug-in module E-SM for integrating the ventilation unit into "EnOcean world" "www.enocean-alliance.org"

KNX

  • Optional KNX plug-in module K-SM allows for connection to building control technology, "www.knx.org".

Heat exchanger

  • Highly efficient cross-counterflow plate heat exchanger made of plastic material (PS).

Frost protection

  • Prevents the heat exchanger from freezing up at low temperatures.
  • By switching off the supply air fan.
  • Recommendation: Combine units with heat recovery with a brine earth heat exchanger.

Energy-efficient fans

  • 2 radial direct current fans, curved to the front in the supply air / outgoing air.
  • 4 ventilation levels can be adjusted continuously between 80.. 320 m³/h (WR 310) / 80.. 470 m³/h (WR 410).

Mounting instructions

  • Easy, very time-saving mounting with the wall bracket included in the scope of delivery.
  • Housing cover is easy to remove using practical magnetic locks.
  • Provide sound absorbers on the inlet and outlet sides.

Electrical connection

  • Ready for service with on/off switch.
  • Prepared for assembly-friendly connection of sensors.
  • Extendible, functional electronics box allows optional additional circuit boards (ZP 1 and ZP 2) to be fitted with ease.

Condensation drain

  • Condensation drain (1 1/2" screen valve).
  • Connection to an optional siphon (DN40).
  • Easy-clean condensate tank integrated in EPP housing.
